This study aimed to determine the distribution area of
tarek (Alburnus tarichi (Güldenstädt,
1814)) and to define how it must be called according to the scientific
name by evaluating its previous studies made by various systematisers
and their reports on its distribution, and by comparing literature knowledge.
The taxonomic characteristics of the collected samples were evaluated and
several measurements and counts were taken on the samples; analfin origin 0-4
scales behind dorsal fin-base; 72-91 lateral line scales; 21-29 gill rakers; 7½-10
branched dorsal-fin rays and 10-12½ branched anal-fin rays. Body and caudal
peduncle was moderately compressed. Body was covered by overlapping scales. Tarek has five different populations in the
Basin. They are Van, Erçek, Nazik and Aygır Lakes and Koçköprü Dam Lake
populations. The main living area of the tarek population is Lake Van; however,
between May and June, mature individuals of tarek enter to tributaries of Van
Lake. Some of them are Karasu, Bendimahi, Deliçay, Zilan, Karmuç, Sapur,
Yanıkçay, Gevaş, Engil, Kurubaş and Akköprü Streams. At the end of study, it
was concluded that tarek should be called as Alburnus tarichi (Güldenstädt, 1814) and it is an endemic fish
species distributed only in Van Lake Basin.
